UNITED STATES JOHN WOJNARSKI, OF CHICAGO, ILLINOIS.

WINDOW-WASHING APPARATUS.

Application filed July 23, 1921. Serial No. 487,009.

T 0 all whom it may concern Be it known that 1, JOHN WOJNARSKI, a citizen of Poland, residing at Chicago, in the county of Cook and btate of Illinois, have invented certain new and useful Improvements in Window-Washing Apparatus, of which the following is a specification.

This invention relates to certain new and useful improvements in window washing apparatus and has particular reference to the provision of means for simultaneously causing a brush to traverse a window pane and means to supply a washing fluid on the pane adjacent the brush, which means is manually operable by a person standing upon the floor of a dwelling and is adapted to be supported upon the sill of a window.

The primary object of the invention is to generally simplify and improve devices of this kind.

Another object of the invention is to provide a window washing apparatus including an upright frame adapted to rest upon the sill of a window and having a vertical shaft journaled therein and extending upwardly beyond the upper end of the same, and means associated with the upper end of said shaft for causing vertical reciprocation of a brush, the shaft being provided with means within convenient reach of a person standing upon the floor of a dwelling for rotating the same.

With the above general objects in view and others that will appear-as the nature of the invention is better understood, the same consists of the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawing and claimed.

1n the drawing, wherein like reference characters designate corresponding parts throughout the several views,

Figure 1 is a rear elevational view of a window washing apparatus, partly broken away, shown operatively associated with a window,

Figure 2 is a view partly in edge eleva-.

tion and partly in section of the device shown in Fig. 1,

Figure 3 is an enlarged fragmentary view partly in edge or side elevation and partly in vertical section of the device shown in Fig. 1 with the water pail and hose connections omitted,

Figure 4 is a fragmentary top plan view of the device shown in Fig. 3,

Figure 5 is an enlarged sectional view taken upon line VV of Fig. 1,

Figure 6 is a similar view taken upon line VI-VI of Fig. 3, and

Figure 7 is a still further similar view taken upon line VII-VII of Fig. 1.

Referrmg more in detail to the several views, the present invention includes a frame consisting of a casting 5 having an upper horizontal plate portion 6 adapted to rest upon a window sil 7 as shown in Figs. 1 and 2 and a depending portion 8 carrying a pump cylinder 9 and arranged beside a handle 10 which is preferably formed as an integral part of the frame casting 5. A vertlcal shaft 11 is journaled at its lower end as at 12 in the upper end of the frame portlon 8 and said shaft extends upwardly through the plate portion 6 some distance above the latter where it also is journaled through a second frame plate 13 which is horizontally disposed above the plate portion 6 and rigidly connected to the latter by a pair of side bars 14. The bars 14 are fixed in suitable openings provided in the ends of the plate 6 and 13, by means of set screws 15 or the like and thus the shaft 11 15 provided with spaced hearings in the frame of the apparatus at the points where it passes through said plates 6 and 13, thereby providing a durable and practical construction of light Weight.

The projecting upper portion of the shaft 11 is formed with a pair of spiral grooves 16 and 17, one being of right hand pitch and the other of left hand pitch and said grooves crossing each other as shoWn clearly in Fig. 3. A plate 18 is slidably mounted upon the upper end of the shaft 11- and also upon a vertical guide rod 19 which has its lower end fixed in the plate 13 and which slidably projects through a suitable opening in the plate 18. The plate 18 is thus effectively guided and supported against tilting strains, and in order to effect vertical movement of said plate 18 upon rotation of the shaft 11, said plate 18 is provided with a cut out as at 20 in which a bracket 21 is fixed, which bracket carries a horizontal roller 22 disposed to engage the grooves 16 and 17 of the shaft 11, the arrangement being such that when the shaft 11 is rotated in one direction the roller 22 is engaged in one of the grooves for causing upward movement of the plate 18, and upon reversing the direction of rotation of the shaft 11,

' the roller 22 engages the other groove and causes the plate 18 to feed downwardly.

The plate 18 is provided upon its forward edge with a brush element 23 in the form of aplurality of bristles suitably fixed as at 24 in a pocket or groove provided in said edge of the plate 18 so as to readily engage the window panes 25 when the plate 6 rests upon the window sill as shown in Figs. 1 and 2.

A bevel gear 26 is secured upon the shaft 11 directly beneath the plate 6 and meshes with another bevel gear 27 fixed upon the inner end of a horizontal shaft 28 which is journaled through the frame casting 5 and is provided with a square outer end 29 adapted for reception of a suitable crank 30 whereby the shaft 11 may be readily manually rotated. Another bevel gear 31 is secured upon the shaft 11 beneath the gears 26 and 27 and this bevel gear 31 meshes with a larger bevel gear 32 which is suitably journaled upon a horizontal stub shaft 33 carried by the frame casting 5. The bevel gear 32 is provided with a crank pin 34 having a pitman 35 pivoted thereto, the other end of the pitman being pivoted as at 36 to a piston rod 37 which slida'bly projects into the cylinder 9 and is fixed to the piston heads 38 in said cylinder.

A drip pan 39 is fastened to the plate 18 beneath the brush 23'and is'provided with a bottom outlet adapted to be connected by means of a hose 40 with a pail 41 so that surplus water from the window pane will be caught in the pan 39 and led to said pail. An inlet hose 42 is adapted to be positioned in the pail 40 and is connected with a check valve 43 provided at the inlet side of the pump cylinder 9 and another hose 44 is connected with the outlet of said cylinder and with a hollow stud 45 formed upon the upper portion of the plate 18. A spray nozzle 46 is also attached to the stud 45 so as to recei'r the washing fluid from the hose 44, and this nozzle includes a transverse head 47 having numerous perforations therein so as to cause the fluid to be projected onto the window pane above the brush element 23.

In operation, the crank 30 is engaged with the square end of the shaft 28 and upon rotation of said shaft the shaft 11 is caused to rotate, through the gearing described, in the desired direction to elevate the brush carrying plate 18 and When the latter reaches its uppermost position, the direction of rotation of shaft 28 is reversed so as to cause the brush carrying plate to lower. Thus, the brush element is caused to reciprocate vertically in contact with the window frame 25 and as this takes place the piston head 30 is caused to be reciprocated within the cylinder 19 so as to draw waterfrom the pail 41 and force the same through the hose 44 to the nozzle 46. The fluid is thus projected onto the window pane as the brush is reciprocated and the surplus water is received in the pan 39 and returned through the hose 40 to said pail 41.

From the foregoing description it is believed that the construction and operation as well as the advantages of the present invention will be readily understood and appreciated by those skilled in the art.

Minor changes may be made in the invention without departing from the spirit and scope thereof.
